Carboxymethyl cellulose (CMC) bụ ihe dị mkpa sitere n'okike polymer ogige nke ejirila ọtụtụ ebe na ụlọ ọrụ seramiiki. Dị ka ihe nkwụnye mmiri na-edozi mmiri, CMC nwere ike imeziwanye arụmọrụ nke ihe ndị dị na seramiiki, kwalite nkwụsi ike na ịdị n'otu n'oge nhazi, ma kwalite àgwà nke ngwaahịa ikpeazụ.
1. Ihe ndị bụ isi nke carboxymethyl cellulose
Carboxymethyl cellulose bụ mmepụta nke cellulose, nke nwere ezigbo mmiri solubility, adhesion na thickening Njirimara site kemịkalụ mgbanwe. Ọdịdị molekụla nke CMC nwere otu carboxyl (-COOH), nke na-enyere ya aka ịmepụta ngwọta colloidal na mmiri nke nwere ezigbo adhesion na rheological Njirimara. Ihe ndị a na-eme ka CMC bụrụ ihe mgbakwunye dị mkpa na mmepụta seramiiki.
2. Ngwa na mmepụta seramiiki
2.1 Nrapado
Na usoro ịkpụzi ngwaahịa seramiiki, a na-ejikarị CMC eme ihe dị ka nrapado. Ọ nwere ike ịkwalite ike njikọ dị n'etiti ụmụ irighiri ihe eji eme ihe ma gbochie mgbawa na nrụrụ n'oge ihicha na ihicha. Site n'ịkwalite ọnụ ọgụgụ nke CMC agbakwunyere, enwere ike ịhazigharị akụrụngwa rheological nke slurry iji mee ka ọ na-arụ ọrụ n'oge ịkpụzi.
2.2 Ọkpụkpụ
CMC nwere ihe ndị na-agbapụta nke ọma na enwere ike iji mee ka viscosity nke seramiiki slurry. Nke a dị mkpa karịsịa maka usoro dị ka spraying na ịwụsa, nke nwere ike hụ na nkwụsi ike nke slurry n'oge ọrụ ma zere ọdịda ma ọ bụ stratification. N'otu oge ahụ, viscosity kwesịrị ekwesị nwere ike imeziwanye mmiri nke slurry, na-eme ka ọ dị mfe iji mejupụta ebu.
2.3 na-ekesa
Na mmepụta seramiiki, CMC nwekwara ike iji dị ka onye na-ekesa iji nyere aka gbasaa ihe ndị dị na seramiiki akụrụngwa ma gbochie agglomeration. Ịrụ ọrụ mgbasa ozi dị mma na-enyere aka melite ịdị n'otu na njupụta nke ngwaahịa seramiiki, si otú ahụ na-emeziwanye ihe eji arụ ọrụ na ngwa anya nke ngwaahịa ikpeazụ.
3. Mmetụta nke CMC na Njirimara Ceramic
Mgbe agbakwunyere CMC, arụ ọrụ nke ngwaahịa seramiiki na-akawanye mma. Nnyocha egosiwo na ọnụọgụ CMC kwesịrị ekwesị nwere ike imeziwanye ike mkpakọ na ike mgbanwe nke ngwaahịa seramiiki. Tụkwasị na nke ahụ, mgbakwunye nke CMC nwekwara ike imeziwanye ihe dị nro na gloss nke ceramik, na-eme ka ngwaahịa ikpeazụ mara mma.
4. Environmental enyi na enyi nke CMC
N'iji ya na polymer synthetic ọdịnala, CMC, dị ka polymer eke, nwere ezigbo ihe nhụsianya biocompatibility na enyi gburugburu ebe obibi. Ojiji nke CMC na usoro mmepụta seramiiki nwere ike ọ bụghị naanị imeziwanye arụmọrụ ngwaahịa, kamakwa ibelata mmetọ gburugburu ebe obibi na mmerụ ahụ mmadụ, nke na-emezu ihe achọrọ nke mmepe mmepe nke oge a.
Ngwa nke carboxymethyl cellulose na ụlọ ọrụ seramiiki na-egosipụta ọtụtụ ọrụ ya dị ka ihe nkedo, thickener na dispersant. Site n'ịkwalite ojiji ya, arụmọrụ na ịdị mma nke ngwaahịa seramiiki nwere ike imeziwanye nke ọma, na-akwalite mmepe mmepe nke ụlọ ọrụ seramiiki. Na omimi nke nyocha na ọganihu nke nkà na ụzụ, atụmanya ngwa nke CMC na mmepụta seramiiki ga-aba ụba.
